摘要
We develop a procedure for the evaluation of strength and crack resistance of reinforced-concrete beam elements based on the approaches of fracture mechanics. A model for the numerical analysis of stresses is proposed and the formulas for finding normal stresses in the reinforcement and compressed concrete fibers are deduced by taking into account the inelastic zones in the vicinity of the crack tip. The established relations are checked experimentally and compared with the formulas proposed by SNiP 2.03.01-84.
